Hiatal Hernia Effects on the Body

The Mayo Clinic describes a hiatal hernia condition as a gap in the body's diaphragm where the stomach is able to enter into the food esophagus (also known as the food pipe). The medical site also notes that "most small hiatal hernias don't cause problems," but large hernias can affect the body.

• Stomach acids contribute to hiatal hernia side effects

Chest Pains

• Larger hiatal hernias may create pains in the chest, sometimes severe pain similar to heart attack symptoms, according to the Mayo Clinic. The strain of lifting large, heavy objects intensifies these feelings.

Belching

• With the introduction of acid into the esophagus, many people with hiatal hernias experience an increase in air buildup that creates belching. The National Institutes of Health suggest avoiding gas-producing foods.

Swallowing Problems

• If the hernia is so large, or becomes twisted, people may have difficulty swallowing. Professional medical assistance is needed in these cases.

Heartburn

• The most common effect of hiatal hernias is heartburn. This condition is created due to stomach gas and may be lightened by avoiding spicy and oily foods and by taking antacids.

Nausea

• Some people with large hernias experience a feeling of nausea when the acid buildup pushes the acids into the food channel. This condition, known as GERD, is most common when lying down, according to the National Institutes of Health.
